Hii There,

Hostel timings can vary widely depending on the specific rules and regulations of the hostel or educational institution you are attending. Typically, hostels have set timings for entry and exit to ensure the safety and security of the residents. You should check with your hostel authorities or refer to the hostel handbook to get accurate information on the timings.

Similarly, the duration you can stay out for library and classes can also vary. Most educational institutions allow students to attend classes and use the library during their scheduled hours. It's essential to check your class timetable and library hours provided by your institution to know when you can access these facilities.

I hope this answers your question.

Thanks
